1.2 For the installer
The precautions described in this document cover very important
topics, follow them carefully.
INFORMATION
This user interface is an option and cannot be used
standalone. It can ONLY be used in combination with a
main user interface. Also see the installation and operation
manual of the indoor and outdoor units.
NOTICE
Improper installation or attachment of equipment or
accessories could result in electric shock, short-circuit,
leaks, fire or other damage to the equipment. Only use
accessories, optional equipment and spare parts made or
approved by Daikin.
WARNING
All field wiring and components MUST be installed by a
licensed electrician and MUST comply with the applicable
legislation.
NOTICE
The user interface MUST be mounted indoors.
NOTICE
When the user interface is used as room thermostat, select
an installation location where the average temperature in
the room can be detected.
Do NOT install the user interface in the following places:
▪ In places that are exposed to direct sunlight.
▪ In places that are near a heat source.
▪ In places that are affected by outside air or air draught due to e.g.
door opening/closing.
▪ In places where the display can easily get dirty.
▪ In places where there is NO easy access to the controls.
▪ In places with temperatures <–10°C and >50°C.
▪ In places where the relative humidity is >95%.
▪ In places where there is machinery that emits electromagnetic
waves. Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
▪ In places where it may be exposed to water, or in generally moist
areas.
If you are NOT sure how to install or operate the unit, contact your
dealer.
